Title: Apparatus for studying the rapid variations of the intensity of a source of light
IPC: G01J1/00
Filed: 1945-12-07
Abstract: 621,482. Optical apparatus. SOC. ANON. POUR LES APPLICATIONS DE L'ELECTRICITE ET DES GAZ RARES-ETABLISSEMENTS CLAUDE-PAZ ET SILVA. Dec. 7, 1945, No. 33203. Convention date, March 21. [Class 97 (i)] A device for studying the rapid periodical variations, in the course of time, of the intensity of a light source, comprises a light-transmitting or reflecting device forwarding light rays emitted by the source, means for imparting to the source and to the said device a relative rotary movement in synchronism with the excitation of the source and such that the light rays describe surfaces of revolution having a common axis and fall upon a screen centred on this axis. As shown in Fig. 1, an electric lamp, enclosed in a casing 1, which is apertured at 2, is connected to a source of alternating current so that the intensity of the emitted light varies continuously during each half period. This light falls on a disc 7, which is apertured at 8 and 9 and is rotatable by an electric synchronous motor 3 in synchronism with the excitation of the source, e.g. by energizing the motor from the same source of alternating current as the lamp. Thus, on a screen or photographic plate 10 there is formed a circle of variable brightness, the brightness of each point on the circumference of the circle corresponding to a particular intensity of the emitted light. When the photographic plate is used, the chinks 8, 9 are in the form of curvilinear triangles so that the respective lengths of circular arcs, which are bounded by two sides of the triangle and are concentric with the axis of rotation of the disc 7, increase as the radius of the circles decreases. In another form, a condenser may be disposed in front of the lamp and the emitted light rays may be successively reflected by two rightangled prisms or plane mirrors, one of which is mounted on the shaft of an electric motor, while the other is carried at one end of an arm mounted at its centre on the motor shaft. Another embodiment is described wherein light is focused on an area of a ring of phosphorescent material carried by a rotating plate so that a ring of light of variable intensity is formed by a lens system on the screen or photographic plate. In the Specification as open to inspection under Sect. 91 the embodiment shown in Fig. 5 (Cancelled) is described. This comprises a cylinder 16, apertured at 17 and 18 and rotatable about an axial light source 15. The excitation period of the source 15 is equal to the time of revolution of the cylinder 16 and observation is made through a cylinder 19. Cylinder 19 may be in the form of a photographic plate. This subject-matter does not appear in the Specification as accepted.

The valve selecting means DSS also selects which of a number of liquid foodstuffs from a number of diet-holding tanks is to be passed through the delivery valves. A pre-settable timer 19, 21 determines the time each delivery valve remains open. A number of further AND gates AND/BA-AND/BZ, one for each of the other AND gates, are interposed between the other AND gates and the valve operating means, and are connected to the counter 21 of the timer. Fluid detectors MLD I, MLD II supply signals to all the further AND gates AND/BA-AND/BZ and to the timer when sufficient foodstuff has been pumped from the main reservoir to supply all the delivery valves at the desired rate, whereby a signal from the fluid detectors causes the timer to start and opens any further AND gates associated with a selected one of the AND gates AND/AA-AND/AZ causing a selected delivery valve to open. The apparatus also includes washing means for automatically washing the reservoir, the ducts, the branch pipes and the delivery valves. The apparatus may be designed to supply further feeding stations by having a further man duct connected to the main reservoir and a number of further branch delivery pipes.

Abstract: 1416681 Firing circuits for thyristors PRINTED MOTORS Ltd 19 July 1972 [19 July 1971 9 Sept 1971] 33767/71 and 42132/71 Heading H3T [Also in Divisions G3 and H2] A triac controls a further triac in the supply circuit of a motor, Fig. 5 (not shown), and enables the further triac to supply the motor with a train of high power pulses in response to a single low power pulse. As shown in Fig. 8, the train is initiated by the application of the low power pulse to the primary winding of a transformer 101 which switches on a thyristor 102 controlling the charging of a capacitor 109 from a full-wave rectified supply 104 ... 108. When the capacitor voltage reaches a predetermined value, a diac 111 switches on to fire a triac 114 controlling the further triac, conduction of triac 114 assisting that of the diac to discharge the capacitor until the diac switches off. Thyristor 102 remains conductive through the action of members 109, 110 and the continued presence of the low power pulse, thus allowing the capacitor to recharge and again switch on the diac to fire triac 114. This operation is repeated until the end of the low power pulse, whereupon the thyristor 102 extinguishes. In the circuit of Fig. 6, high frequency output pulses are obtained from terminals 142, 143 by applying a high frequency A.C. supply to parallel-connected diode, resistor triac circuits 134, 136, 130 and 135, 137, 131, one or other of the triacs being fired by a positive or negative signal applied at terminal IN via diodes 132, 133. This signal is derived from the error signal of a process controller (see Division G3) and thus produces positive or negative half waves of the high frequency supply across the resistors 136, 137, which in turn control transistors 138, 139 to produce corresponding pulses at the terminals 142, 143 for application to a firing unit for thyristors controlling a D.C. electric motor, Fig. 7 (not shown).

Title: Process of converting substantially uncracked petroleum, shale oil or the like into an oily menstruum for making rubbery products
IPC: C08L91/00
Filed: 1931-12-05
Abstract: An uncracked hydrocarbon distillate is mixed with a liquid obtained by fermenting cellulosic and sugary materials in the presence of water, and the resulting emulsified mixture is subjected to aeration and actinic light until the water is evaporated, leaving an oil which may be converted into a rubber substitute.  Suitable hydrocarbon distillates are prepared by distilling a crude petroleum asphalt base or shale oil, freed from light hydrocarbons, in vacuo, with low pressure steam admitted into the vapour space, and collecting the fraction boiling from 280 to 370 DEG  C.  The fermentation liquid is prepared by mixing finely chopped hay with water and molasses, and allowing the mixture to stand two weeks.  The liquid is then filtered.  Hay may be replaced by bagasse, silage, straw, corn stalks, &c., and the molasses by malt sugar, glucose, syrups, honey, sorghum cane, &c. The emulsified mixture is cascaded over trays or boards at 30-45 DEG  C., exposed to air and sunlight or to the rays of a mercury vapour lamp.  The resulting water-free oil is filtered and converted into a rubber substitute by adding a metal oxide or carbonate and heating at 80-90 DEG C. with sulphur or sulphur chloride.  Metal oxides &c. specified are magnesium or calcium oxides, or magnesium, calcium or sodium carbonate.  Small amounts of natural rubber or rubber latex or fillers or colours such as zinc oxide, vermilion, ultramarine, lamp black, &c. may be incorporated. The sulphurized product may be submitted to further vulcanization and the products may be moulded and used in the manufacture of rubberized fabrics, tyres, inner tubes, shoe heels, or vulcanite.
